This antibody meets EpiCypher’s “CUTANA Compatible” criteria for performance in Cleavage Under Targets and Release Using Nuclease (CUT&RUN) and/or Cleavage Under Targets and Tagmentation (CUT&Tag) approaches to genomic mapping. Every lot of a CUTANA Compatible antibody is tested in the indicated CUTANA approach using EpiCypher optimized protocols and determined to yield peaks that show a genomic distribution pattern consistent with reported function(s) of the target protein. FOXA1 antibody produces CUT&RUN peaks above background primarily in intronic, intergenic, and promoter regions (Figure 1) that overlap with known FOXA1 DNA-binding motifs (Figure 2).

Validation Data

Figure 1: FOXA1 peaks in CUT&RUN
CUT&RUN was performed using 500,000 MCF7 cells with 0.5 µg FOXA1 antibody. Peaks were called using MACS2. (A) Heatmap showing FOXA1 peaks relative to IgG negative control antibody (EpiCypher 13-0042) in aligned rows ranked by intensity (top to bottom) and colored such that red indicates high localized enrichment and blue denotes background signal. (B) The number of peaks which fall into distinct classes of functionally annotated genomic regions is plotted.

Figure 2: FOXA1 transcription factor binding motif analysis in CUT&RUN
(A) Homer analysis determined that the FOXA1 consensus motif, represented as a sequence logo position weight matrix, was enriched under FOXA1 CUT&RUN peaks. (B) The number of FOXA1 peaks containing consensus motifs from panel A is represented by a Venn Diagram. (C) Three representative loci showing overlap of FOXA1 peaks with consensus motifs (IGV).

Figure 3: Western blot detection of human and mouse FOXA1
Whole cell lysates were isolated from MCF-7 and HeLa cells using NETN lysis buffer. The indicated amounts (µg) of lysate were loaded onto 4-20% SDS-PAGE gel and analyzed under standard western blot conditions using FOXA1 antibody (0.1 µg/mL).

Figure 4: Immunoprecipitation of human FOXA1
EpiCypher FOXA1 antibody (6 µg) was used to immunoprecipitate whole cell lysates isolated from HeLa cells using NETN lysis buffer (1 mg per IP). A negative control IgG antibody and positive control antibody to a different FOXA1 epitope (Bethyl Laboratories) were also used to demonstrate specificity of the IP. Immunoprecipitates were loaded onto 4-20% SDS-PAGE gel (20% of IP loaded) and probed via western blot with EpiCypher FOXA1 antibody (1 µg/mL).
